1. An apparatus comprising:
a light source;
a first surface with a material that causes splitting of light rays from the light source to reflect first light rays and transmit second light rays;
at least one second surface with a material that causes splitting of the second light rays transmitted from the first surface to reflect third light rays; and
light-reflecting surfaces configured in a plane that is oblique to the first and second surfaces, wherein the first and third light rays are reflected by the light-reflecting surfaces towards an imaging surface.
